Siskiyou Pass is probably one of the most frequently plowed and sanded mountain passes in the western states. Even in heavy snow, it's rarely closed for more than a couple of hours at a time and the sanding keeps the ice build-up to a minimum.

We had family in Prescott for a couple of years, and I'd second Larry's route suggestion. We used to go over the pass into Kingman then south to Prescott.

511 Traffic Information

I'm offering a simple solution if you have a cell phone. Dial 511 on your cell phone and follow the prompts, and you can easily get current road conditions for your route. You don't need a smart phone for this, you just get recorded information on current conditions.

If you have a smart phone, just do a search for "ODOT" and you can look at current conditions using their cameras on I-5 at the summit of Siskiyou Pass.

Weather forecast are pretty reliable these days, hang out for a day if the pass is snowed in, and for goodness sakes don't do any cell phone work while you are driving. Pull over or let your co-pilot help. All the best with your trip. Hans

You can go online to the different states to their road websites and get the information and the phone numbers. The best information from me is to be smart and know when to stay put if you get bad road information. The Gravevine can get snow but you can get off I-5 at Bakersfield and go East 58 to 395 and go south to I-15 to I-10 and East to Palm springs.

it's the highest elevation on I5, at only 4,310ft.

I went over that pass in 1988 in a 26' U-Haul towing a twin axle trailer. As I progressed uphill from the California side drizzle changed to sleet and then to ice at the top. I had no tire chains and it took me an hour to get to the bottom! My wife had driven ahead and I found her down the highway parked in an Oregon rest area crying her eyes out because she thought I must have had a wreck and died!

I guess what I'm trying to say is, plan your route in advance and before you go over any high passes make sure that you check for road conditions on top of the pass as well.

If you want to stay pretty much ice/snow free you could go down through California and cross to Florida on I-10 (a long trip). As for driving through LA and its nightmare traffic, the last time I drove my RV through LA I did it at 2:00am and it was very nice.

BTW I wintered over in southeast Arizona last year and at least half the people in my park were Canadian.
